well...
i think EITA is your best friend for this build,for advice and test with his parts.
I don't know before many and many differents tests, shocktech frame is a....crap because out of std.
i can't do nothing for you apologize.
For your frame/body screw,you need a ccm lenght screw (rear),and normal wgp lenght (front/bridge).
For internal frame/trigger adjust screw,you can asking to Sir Steve Belsales when you buy your Belsales parts or made an hand milling with PE on/off asa headless screw.
For springs, pencil spring for trigger plate and classic for sear.
I phone today at french shop and.....i'm lucky! It's an *******,busy,he don't have the time for watching if they are available,i make another call next tuesday.
